Keyboard-driven Mini-Search/Replace

The Edit menu contains a Mini-Search sub-menu that enumerates the
available keyboard-driven search options. These are normally initiated
with the keyboard command sequences shown in the menu and can be
controlled entirely by using the keyboard. All interaction with the
mini-search manager occurs using data entry areas displayed on demand at
the bottom of the IDE window.

The implementation of the mini-search manager is very close to the most
commonly used search and replace features found in Emacs, but it is
available whether or not the Emacs editor personality is being used.

The following search and replace features are available in this facility:

Forward and Backward -- These display a search string entry area
at the bottom of the IDE window and interactively search forward or
backward in the current source editor, starting from the current cursor
position. The search takes place as you type and can be aborted with
Esc or Ctrl-G, which returns the editor to its original
cursor location and scroll position.

Searching is case-insensitive unless you enter a capital letter as part of
your search string. To search repeatedly, press Ctrl-U (or Ctrl-Sinemacskeyboardmode)tosearchforwardand``Ctrl-Shift-U (or Ctrl-R in
emacs mode) to search in reverse. The search direction can be changed any
number of times and searching will wrap whenever the top or bottom of the
file is reached. You can also enter Ctrl-U (or Ctrl-S in emacs mode) or
Ctrl-Shift-U (or Ctrl-R in emacs mode) again initially while the search
string is still blank in order to call up the most recently used search
string and begin searching forward or backward with it.

Once the mini-search entry area is visible, Ctrl-W will add the current
word in the editor to the search string. Pressing Ctrl-W more than once
while the mini-search entry is visible adds additional words from the editor
to the search string.

Selection Forward and Selection Backward -- These work like
the above but start with the selection in the current source editor.

Regex Forward and Regex Backward -- These work like the above but
treat the search string as a regular expression.

Query/Replace and Regex Query/Replace -- This prompts for search and replace strings in
an entry area at the bottom of the IDE window and prompts for replace
on each individual match found after the cursor location in the current
source editor. Press y to replace or n to skip a match and move
on to the next one. The interaction can be canceled at any time with
Esc or Ctrl-G. Matching is case insensitive unless a capital
letter is entered as part of the search string. Searching is always
forward and stops when the end of the file is reached, without wrapping
to any un-searched parts between the top of the file and the position
from which the search was started.

Replace String and Replace Regex -- This works like the above command but immediately
replaces all matches without prompting.
